ments n talking machines. 'particularly to.

means for automatically starting the driven record supporting disk.

One object of my invention is to provide a self-Starter for the record support whereby at a redetermined time the driven support w l be 'released and the machine i My inveition also has other objects in view which will be obvious from the d& tailed. description thereof.

The same s illustrated in the accompanyingdrawings which form part of this specification and in which similar reference characters denote `eorresponding parts, Figure 1 being a plan view of the machine with the cover removed and showing parts of the starting and stopping mechanism; Fig. 2 is a sectional-plan view on line 2--2 of Fig. 3 of the machine showing the parts of the starting and stopping mechanisms 'located inside the cabinet or box; Fig. 3 is a cross section on line 3-3 of Fig. 2; and Fig. 4 is a vertical section on line 4--4 of Hi 3.

Referring to t e drawing and particularly to Figs. 1-8, 1 denotes the cabnet or box of the talking machine which may be of any suitable Construction. 2 is the movable or rotary base or support for the records 3 which base, as usuall is mounted on the spindle 4 and driven rom a mechanism 5 located within the cabinet or box. Since the driving of the machine does not constitute part of my invention, a detailed descrilption of the driving means is dispensed wit 6 denotes the horn or hollow arm which ce-ries the sound box 7 and Stylus &and which is mounted in the cabinct in a well known manner, the samjc communicating with the hollow l' of the cabinet from which the sound issues As usually, the driven base 2 of the records 3 is arrested and held against rotation by a brake member 9 which is adapted to be pl'essed against the outer circumferencc of the disk or sup port 2.

My invention resides in the means for operati the brake so as to release the same a! a predcternined time.

To accomplisl this I provide a clock 12 which is suitably nounted within the cabi nel so that its face ((lizl with poiuters) is i i exposed to the outside. The clock used for aceonplshng my ob ect may be of a similar constructon :s an ordnary alarm clock,

Patcnted Dec. 25, 1917.

i. e equipped with a spring operated or 'otherwise driven mechanim which' is control-led by the clock mechanism so that at a. previously set time the said mcchaisn will be released 'from' the clock and he set into operation. As au alarm is not required; the alarm proper (hammer and bell) may be omitted'. For the purpose of this invention-the clock controlled mechanism may consist simply of a suitably driven spindle 13' which for simplicityls sake I shall -efer i to hercafter as the starting 'mechanisn or spindle and which has the usual ne'ans wher'eby its operation is controlled fron the clock. In the present example the clock 4 is shown mounted in one of the walls of the eabinet. The s indles 13, 10; 17 and 18 for winding up t e starting spindle 13', for the adjustmeut of the ,pointe-s, for the starting mechanism and for winding up the clock respcctively are'all extended from 'the back of the clock through the cabinet' to project outwardly froni the 'opposile wall and to carry knobs 13", 16 17' and 18' respectively for the manipulation oi the said spndles from outside 'the casig or cahinet, in order not to burden the spindle of the painters, the same is composed of two sectons, to wit 16 and 16 ,which normally are held dscngagcd by a spring 113', but which cau be couplcd by means of a. eoupling 10 'of any suitable constructiou when it is desired to set the pointers. The section 16" of the spindle of the poiutcrs may be movably supported in the cabinet by means of a platc 19 which is forncd with slccvc-like projections 19', 19 engaging around the spindles 18 and 17 respectively.

The brake block 8 is fixed to an angular lcvcr 8', 8 which is fulcruncd at 8 in a slot 1' made in the top of the cahineh 9 is a metal plate fixed to the top of the cabinet over said slot and having a corresponding slot 9' through which the upper arm 8' of the lever projects outwrdly. The lower arm 8' projects downwardly into the cabinet and has attached to it one end of a spring 11, the other end of which is fixed to the horizontal arm 10"of a bracket 10 fixed to and projectin from the bottom of the metal plate 9. T e spring 11 has the tendencyto draw the brake arm into operative. ostion -to press against the rotary base*2. ly.- mounted on the spindle .13 is a sleeve 14 which near one end is formed with an annuhr 'shoulder 14' and at the other end is provided with teeth or can-shaped projections 14 The enlarged portion 13' of the starting sp'indle 13 is provided with similar pro ectons 13 as those of the sleeve 14:, which coperate with the sleeve 1-1 to hring about'a coupling of thelatter with the startiig spindle 13. The sleeve 14 is actizted by a spring 15 one end of which is fixed to the spind e 13 and the other end of which abuts against the rem-.end of the eouplin sleeve 1-1. This spring tends to constant y press thesleeve 14 iuto en 'age- 26 ment with the part '13' 'of the spind e 13.

A rod or link 20, the 'ends '20' and-?0 of which are bifurcated, is pivotally connected at one end to the sleeve 14 and at the other end to the lower arm 8 of the brake lever. When the sleeve 14' is uncoupled from the starting spindle 13" it will be allowed to Swing on the spindle 13 and owing to the force of the ring 11 the rod or lnk -will belowered. T e brakewill then be in operative position. The teeth of' the coupling parte 14', 13' are so shaped that when the spindle 13 is at rest or is rotated in the di- .rection to wind up the startin mechanism,

they will slide-over one :mot i'er and the downward pull of the spring will hold the breke in' operative 'ton. But when the 'spindle 13 on its re ease from the clock will be set into rotation in the opposite direction,

the teeth 13 will be coupled with the teeth 14' and thereby cause the sleeve to turn in the same direction, thereby raising the rod or link against the pull of the spring 11,

in consequence of which the bra'ke will be moved away from the rotary and driven base 2, permitting the latter to start its mo tion. Thus at a set time, the machine will be automticall started through the medium of the c ock controlled spindle 13 which positively moves the brake 8 into inoperative position.

The starting mechanism 13, 13' may be` temporarily cut out in the sual manner through the adjustable stop projeeting outwardly from the back of the clock and movablc thrp h a circularly shaped slot46. Connccted with this stop 45 'is a lever 22 fixed to the lower end of a vertical rod or spindle 21 which is rotatively supported in a brachet 21' fixed to the back of the 6 clock. The rod 21 is adapted to project outpower will commence to revolve.

wardly through :the plate 9 and' .to carry on its outer end a lever or handle 24 whereby -the adjustment of the stop 45 into alarm' fnme`23 which is lon itidinally recessed, as

at 23', through whic fixed on the rod 21. This shifter frane 23' when moved by the arm'22' outwa'rdly cnn,

be brought to restagainst the shoulder of the coupling sleeve' 1-1 to hold the letter' out of engagement. The shifter plate or frane 23 and arm'22' serve as an auxiliary stop mechanism. Thus, when the automatic operation of the brake is n'ot desired; the shifter frame 23 may be moved to en age the collar 14' of the coupling 14 and to thereby lock -it out of engagement with the part 13'.

\Ve will assume that the shifter frame 23 is in' normal position-in which it leaves the sleeve 14 free to swin on the spindle 13 and to move longitudina ly thereon under the influence of the s ring 15; and we will assume that the bra 'e lever is in operative position, that is, holding the record sup ort t' rest. -Whilc the sleeve 1-1 is uncoupl from the spindle 13, it is capable of swinging feely on the spindle 13 so that the link 20, under the influence of the spring 11, will he lowered, while the brake is on. .As soon, however, as the spindle 13, is released and sot into operation bythe'clock mechanism at a. pre-determined time the slceve 14 will enga with itstecth 1-1', the teeth 13= of the spn e andvbe carried along with it in the same direction. In consequenoe t-hereof, the link 20 will be raised and positively swing the lever 8', 8 against the tension of its spring 11, sq as to remove the brake 8 from the record support, which then .under its motive If it is not dcsired to have the broke operat'ed automatically from the starting spindle 13, the shiftr frane 23 through the medium of the rod 21, and the arm 22' is displaced so :s to move the 'sleeve 14 out of contactnvith the teeth 13 and retain it in this position as loug as the automatic control is not desired, so that the operatio'i'of the spiidle 13 ndcthe control of.-the clock nechanisn will have in efect on the breke. Since various modifirations may be made in the constrnction without deviating from projects an arm 22'.`

the principle of my intention, I'do not wish mounted on said spindle, coupling means pe'mitting the self-coupling of said sleeve to said spndle, a link connectin said member to said breke and adapte when the spindle is set into notion, to positively move said breke into operative position.

2. In a talking machine, the oombination with the driven record support, of a breke for the letter, a clock controlled spindle, adapted to operate only at times, a rotary and longitudinally mova'ble spring actuated sleeve on said spindle, coupling means allowing the self-coupling of said sleeve to said sp ndle when the letter revolves in a. certain direction, said sleeve being 'onnected to said breke so :s to positively move the lat ter into operative position when the spindle is set nto operation.

3. In. a talking machine, the combination' with a driven record support, of a. spring ;ctueted brzke for the letter, a starting mechanism comprsing a clock controlled spinclle, a sleeve rotatively and slidabl monnted on said spindle and ca'pable of sel coupling to said spindle when the letter revolves n a certaindirection, and a rigid member pivotally connecting said breke to said sleeve and which when the letter is coupled to and revolves with said indle will move the breke against the tenson of 30 its spring force awayfrom said record suport.

4. In a talking machine, the combination with a driven record support, of a. breke' in- .cluding a spring actuated lever carrying 35 said breke, a starting mechanism comprising a 'clock controlled Spndle, a sleeve rotatively and slidably mounted on seid spindle and capable of self-coupling to said 'spndle when the letter revolves n a certain direction, and 40 a, link ivotally connected :it-one end to said breke ever and at the other end-to said sleeve and 'adapted when the letter iscou- .pled to and revolve's with said spindle to move said brake lever away from said record support against the tension of its spring force. i

In testimony whereof I aflix mysigneture in the presence of a witnes;
